General Safety Information

WARNING
“Maintenance interval depends on the usage and riding circumstances. Clean regularly the
chain with an appropriate chaincleaner. Never use alkali based or acid based solvents such
as rust cleaners. If those solvent be used chain might break and cause serious injury.”
• Use the reinforced connecting pin only for connecting the narrow type of chain.
• There are two different types of reinforced connecting pins available. Be sure to check the table below before selecting
which pin to use. If connecting pins other than reinforced connecting pins are used, or if a reinforced connecting pin or
tool which is not suitable for the type of chain is used, sufficient connection force may not be obtained, which could
cause the chain to break or fall off.

• If it is necessary to adjust the length of the chain due to a change in the number of
sprocket teeth, make the cut at some other place than the place where the chain has
been joined using a reinforced connecting pin or an end pin. The chain will be
damaged if it is cut at a place where it has been joined with a reinforced connecting
pin or an end pin.

• Be careful not to let the cuffs of your clothes get caught in the chain while riding,
otherwise you may fall off the bicycle.
• Check that the tension of the chain is correct and that the chain is not damaged. If the tension is too weak or the chain is
damaged, the chain should be replaced. If this is not done, the chain may break and cause serious injury.
• It is important to periodically check the tightening torques for the crank arms and pedals. After riding approximately 100
km (60 miles), re-check the tightening torques. If the tightening torques are too weak, the crank arms or pedals may
come off and the bicycle may fall over, and serious injury may occur as a result.
• Check that there are no cracks in the crank arms before riding the bicycle. If there are any cracks, the crank arm may
break and you may fall off the bicycle.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn or damaged parts may
cause the bicycle to fall over and serious injury may occur as a result. We strongly recommend only using genuine
Shimano replacement parts.
• Obtain and read the service instructions carefully prior to installing the parts. If adjustments are not carried out
correctly, the chain may come off and this may cause you to fall off the bicycle which could result in serious injury.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.

Inserting the inner cable
Insert the inner cable into the outer casing from the end with
the marking on it. Apply grease from the end with the
marking in order to
maintain cable operating
efficiency.
Marking
Example:
Cutting the outer casing
Adjusting the grip width
When cutting the outer casing, cut the opposite end to the
end with the marking. After cutting the
outer casing, make the end round so
that the inside of the hole has a
uniform diameter.
It is recommended that you adjust the grip widths of the levers
to the most comfortable widths for gear shifting and braking.
Attach the same outer end cap to the cut end of the outer
casing.

• If the chain is on the smallest or intermediate chainring, there is the danger of injury from the tips of the teeth on the
largest chainring.
• In addition, if pedaling performance does not feel normal, check this once more.
• Before riding the bicycle, check that there is no play or looseness in the connection. Also, be sure to retighten the crank
arms and pedals at periodic intervals.
• When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from sticking. Use a
torque wrench to securely tighten the pedals. Tightening torque: 35 - 55 N·m {305 - 479 in. lbs.}. The right-hand crank
arm has a right-hand thread, and the left-hand crank arm has a left-hand thread.
• Do not wash the bottom bracket with high-pressure jets of water.
• If you feel any looseness in the bottom bracket axle, the bottom bracket should be replaced.
• If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
• If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.
• You should periodically wash the chainrings in a neutral detergent and then lubricate them again. In addition, cleaning
the chain with neutral detergent and lubricating it can be a effective way of extending the useful life of the chainrings and
the chain.
• The cuffs of your clothing may get dirty from the chain while riding.
• If the chain keeps coming off the chainrings during use, replace the chainrings and the chain.
• When the chain is in the position shown in the illustration, the chain may contact
the front chainrings or front derailleur and generate noise. If the noise is a

• This front derailleur is for triple front chainwheel use only. It cannot be used with
sprockets
the double front chainwheel, as the shifting points do not match.
• When installing the top route type, choose a frame that has three outer casing

holders as shown in the illustration at right.
• Use an outer casing which still has some length to spare even when the handlebars are turned all
the way to both sides. Furthermore, check that the shifting lever does not touch the bicycle frame
when the handlebars are turned all the way.
• Grease the inner cable and the inside of the outer casing before use to ensure that they slide
properly.
• Operation of the levers related to gear shifting should be made only when the front chainwheel is
turning.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For maximum performance we highly recommend Shimano lubricants and maintenance products
• For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a
professional bicycle dealer.

Use a handlebar grip with a maximum
outer diameter of 36 mm.
